TO ALL WHM I'I' MAY CONCERN: y

Be it knownthat I, JOAB H. WOOSTER, of Stryltersville, Wyoming county,and State of New York, (assigner to myself and Robert Dunbar, ofBuffalo, New lYorli,) lia-ve invented a certain new .and improvedGovernor for Steam'Engines; and I do hereby declare that the followingis a full .and exact description thereof, reference being had to theaccompanying drawings, in wl1ich- Figure I is a side elevation. i

Figure II is a top plain view.

Figure III is a. detail .sectional view.-

The nature of this invention consists, first, in the arrangement of thegovernor-balls upon arms or rods radiating from the driving-shaft of aysteam engine, and the connection of thearms'of such balls with theeccentric, which operates the cut-oi'. valve in manner herein set forth,so that the outward movement of the balls will he communicated to theeccentric'and thereby control the cut-o'; second, in the eccentric beingloosely arranged en the driving-shaft, in connection with the governor,the governor holding the eccentric and changingand controlling its lead.i i

Letters of. like name and kind refer to like parts in each of thefigures.

The governor-balls A are placed upon the radial arms B B in a manner toallow them to move outwardly and inwardly upon saidarrns.. vThe saidarms are attached to and radiate from the.driving-shafty at anyconvenient location. They may be attached by means of a hub, orotherwise, or they may be attached between'the spokes of the ily-wheel,as shown in the drawings, the place of attachment being a matter ofchoice or convenience. A spiral spring, G, is connected with eachgovernor-hall and coiled around the radial arm, and also attached at itsopposite end to the lug el, secured between two adjusting screw-nuts c2near the hub. D represents the eccentric, which is placed loosely uponthe shaft, and is connected with the cut-ofi' valveE by means oftheconnecting-rod E. The eccentric has a i1u b,d, projecting from the.side nextto the governor-balls. F is theieccentric ofthe slide-valveF2, whicheccentric is'inadc fast on the shaft, and Fl is itsconnecting-rod. G represents a `collar, having crank-like extensions h,which is connected to the hub d of the loose eccentric b'ymeansoi' theset-screws g. The-crank extensions of the collar are each `connected tothegovernor-ball by means of the rods h'.

rlhe adjustable springs are made to oppose a given force't'o the outwardmovement of the governor-balls.

The eccentric, which is in connection' with the cut-ofi` valve, beingplaced and used loosely upon the shaft, and being connected with thegovernor, and being held and controlled by 'the governor, as beforedescribed, itis evident that the governor will act directly upon theeccentric to change and determine its lead, and thereby control thecut-oli.

All the parts may be set so as to give any required velocity to thc`driving-shaft, and so as to cutoff steam atlany required part'of thestroke. Y

What I claim as my invention, and desire to secure by Letters Patent, is

1. The arrangement of the governor-balls A, sliding` on rods B B,radiating from the driving-shaft of a steam engine, and held by coiledsprings C, their arms h connecting with the-eccentric, which operatesthe cut-oli` valve in such manner that the outward movement of the ballswill be communicated to the eccentric and thereby control the cut-oli',substantially as described. Y

2. The connection of the rod z to the eccentrics, consisting of the hubd', collar G, with crank-like extensions L, connected to the hub d bythe set-screw g', constructed and arranged as set f'orth.4
